MacBook Pro 16" i9 HDMI Interlaced output not working

I can't seem to output via HDMI from my MacBook Pro 16" i9 at 1080 60i. Even though I have the display preferences set for 1080 60i, the computer outputs 1080 60p. I tried forcing it to 60i using a preference pane called SwitchResX and I still can't output interlaced, only progressive, regardless of an interlaced setting. I have several devices that tell me the output is progressive and not interlaced. Is this a bug? is there a work around?

chained adapters may not work. (Get help with video issues on external displays connected to your Mac - Apple Support)

If you're using more than one video adapter to connect your display (the adapters are "chained" together), try connecting the display using only one adapter if possible. Some video adapters can't be connected together. For example, a mini DisplayPort to DVI adapter can't be connected to a DVI to HDMI adapter.

Hope it helps.

Is there any advantage of using 60i over 60p?

I am trying to feed a data video HD switcher via a built in DVI port that only excepts 60i. It will not except a progressive signal.
